Terms of Service

Effective date: October 20, 2026

These Terms of Service apply when you use SoundToMIDI.com, including the free audio-to-MIDI converter, optional music arrangements and credit-funded project exports. By using the service or purchasing credits, you agree to these terms.

1. The service

SoundToMIDI converts compatible audio into MIDI in your web browser. Raw MIDI downloads are free. A Music Export Pack is an optional one-time purchase at the price shown before checkout. It includes the current edited MIDI, an automatic piano score draft in PDF and MusicXML, a labeled piano-key note-map PNG, original-speed and half-speed synthesized practice WAVs, a note list CSV, and an export guide (eight files), available as a ZIP or individual files. Conversion and Raw MIDI remain free without an account. A guest can buy the current export pack directly for US$2.99 without an account; download in the same browser within seven days. Google sign-in is required for credit purchases and cloud saves. New accounts receive 5 welcome credits, usable for one project export OR one arrangement. One shared balance funds both services: a complete project export costs 50 credits; a music arrangement request costs 5 credits, including the audio versions returned by that request. One-time packs contain 50 credits for $2.99/€2.99 or 100 credits for $4.90/€4.90 at the amount and currency displayed before checkout. Purchased credits do not expire. There is no subscription or automatic renewal. Every new conversion is a project; its export unlock includes subsequent edits and downloads. Existing balances and unlocked projects remain valid. Older credit grants retain their original export value (5 older credits per export); new purchases use 50 credits per export. Previously placed orders are fulfilled using their original terms.

Listen to the MIDI and preview the score before purchasing. Notation uses a fixed tempo, a sixteenth-note grid and a suggested pitch-based hand split. Notation settings may add leading rests or change the score layout, but do not change the edited MIDI timing. The score is an automatic draft, not a professionally corrected arrangement; notes, rhythm and hand assignments may need revision. Tuplets, pedal, fingering and expressive tempo changes are not inferred. Empty staves are omitted; accompaniment is not added. Practice WAVs use a simple reference instrument synthesized from the edited notes, not your original recording or a sampled acoustic piano. Half speed preserves pitch. WAV exports support passages up to ten minutes of notes.

Optional music arrangements

Arrangements generate new audio from your recording and chosen style through Kie. They are not chord detection, isolated stems, MIDI output, or a guaranteed faithful rendition. Melody, timing, instrumentation and duration may change. Fixed demos illustrate possible results, not a promise for every input. Listen before downloading or publishing.

Credits are reserved when generation starts. A confirmed processing failure returns the 5 credits to your original balance. If submission or delivery is uncertain, we reconcile the existing job instead of automatically creating and charging for another. Contact support if it remains unresolved. A new generation is a new paid operation; downloading an already generated result does not consume credits. Statutory remedies remain available.

Use only audio you own or have permission to submit to an external generation provider. We do not promise copyright ownership, exclusivity or clearance for generated audio. You remain responsible for the rights needed for your intended use.

2. Your files and privacy

Audio conversion runs on your device. Saving a project uploads its edits, settings and MIDI files to private cloud storage. In the local converter, original audio is uploaded only if you select the audio-backup checkbox; for videos, only the decoded audio track is backed up as WAV. Save again after changes. Unchecking audio backup and saving removes the existing audio backup. Cloud storage supports up to 200 projects per account, with up to 4 MB of project data and MIDI plus an optional audio backup up to 25 MB per project. Saving uses no export credits; downloading edited MIDI and the export pack still requires an unlocked project.

3. Paid download delivery and availability

Orders and unused credit balances are stored with your account and can be recovered by signing in to the same Google account. Cloud-saved projects can be reopened on other devices and exported locally. Projects that you did not save to the cloud cannot be reconstructed from a payment receipt alone. Keep downloaded backups. Deleting a cloud copy removes its project data, MIDI and any audio backup, not the purchase record or entitlement, and does not refund used credits.

Legacy purchases made before account exports launched remain tied to the original result in the original browser. Their local tasks last up to seven days and can be removed earlier by browser settings. Their existing verification links remain supported; they do not automatically become account export packs. If payment succeeded but files are unavailable, do not pay again. Contact contact@soundtomidi.com with your receipt and approximate payment time for recovery help or an appropriate refund. Do not send your audio or full card number.

4. Payments

Payments are processed by Stripe. The checkout page shows the one-time price and currency before you pay. We do not receive or store your full card number.

5. Your responsibilities

You may only upload or process audio that you have the right to use. You are responsible for how you use, publish, or distribute generated MIDI and for complying with applicable copyright and other laws.

6. Conversion results and service availability

Audio transcription is an automated process and may produce missing, extra, mistimed, or incorrect notes. You should review the result before relying on it. We may update, suspend, or discontinue parts of the service, but this does not remove any rights you have for a purchase already made.

7. Consumer rights

Nothing in these terms excludes or limits any consumer right or remedy that cannot legally be excluded or limited. If a paid digital download is not supplied as described, contact us so we can investigate and provide an appropriate remedy.

8. Changes to these terms

We may update these terms when the service changes. The effective date above identifies the current version. Changes apply prospectively and do not reduce rights attached to an earlier purchase where the law does not allow that.
